Did any members of NATO get attacked?

As of my last knowledge update in October 2023, NATO members have experienced various forms of aggression, but a direct military attack on a NATO member state has not occurred. The most notable incident was the 9/11 terrorist attacks in 2001, which prompted NATO to invoke Article 5 for the first time. However, the alliance has been involved in various operations and missions in response to threats and conflicts, including Russian aggression in Ukraine, which has heightened security concerns among member states.
